Rocket League, And its Encrypted UPKs

Sat, 12 Mar 2016 02:47:54 +0000

So im very new to the modding scene, and tackling a game like rocket league doesnt seem to be smart, but im making leaps and bounds with modding this games files.
What I am interest in is modding the upk files that contain all the data within "CookedPCGame"
What i have managed to do is use a decrypter found on reddit, which converts the UPK files to Upk.unpacked files viewable with UEexplorer
I have managed to extract all textures from the unpacked files to TGA format, including textures, lightmaps and materials
What i would like to know is:
Is there any way to recompile the files back into the UPK format?
I understand that Encrypted UPKs cant be read usually, but was wondering what would be needed to read/edit the key for each file.

I have managed to edit the .wem files within rocket league to play custom radio by using Wwise to create new .wem files using your own music and am working on creating new .Bak files in order to edit the sound effects for the game.

If anyone has any useful threads on encrypted UPKs and repacking it would be much obliged

MKKE .xxx files

Mon, 24 Nov 2014 10:20:58 +0000

Hi
I'm trying to open some .xxx files from Mortal Kombat Komplete Edition, lets say a Character file. I've decompressed it, renamed it to .u and made sure the UE explorer was set to Console before opening. Here's what I get:

"Thrown by:LoadPackage
at UEExplorer.UI.Tabs.UC_PackageExplorer.LoadPackage()
at UEExplorer.UI.ProgramForm.LoadFile(String fileName)System.IO.EndOfStreamException: Unable to read beyond the end of the stream.
at System.IO.BinaryReader.FillBuffer(Int32 numBytes)

at UELib.UnrealLoader.LoadPackage(String packagePath, FileAccess fileAccess)
at UEExplorer.UI.Tabs.UC_PackageExplorer.LoadPackage()
Unable to read beyond the end of the stream."

Which is a real darn shame since I've used this tool to mod an incoherent pile of mess that was Aliens Colonial Marines, and pretty extensively too. I thought MK was supported? Anyways, can't open any file so far from this game. Any help?

I've sent a report too...

Hawken - sound mod

Fri, 09 May 2014 06:34:09 +0000

Hey eliot / anyone

Really, I just wanna swap out a few sound files for the weapons, and with some searching and hard work was able to find the upk with all the sounds in it, and can export them as .oggs, yet how do I repack a folder directory?
Or better yet replace it within your(or another) program?

The upk doesnt want to load with either your UE or the new UDK.

I wouldn't mind throwing some donation your way, i have hit a wall and Im thinking it might be impossible. I can send you any files if you wish.

Bioshock Support

Can we have Bioshock 1 and 2 support? Please.

America's Army: 2.5 & 2.85

Sun, 25 Aug 2013 17:17:47 +0000

Both games are partially supported by Explorer, but it will be nice if you can make full support.

Some errors:

Quote:/* An exception occurred while decompiling hidecategories. */

var @NULL PendingTouch[26125];
var int Damage[26125];

local @NULL Start[26125], Dir;
local bool ReturnValue[26125];

SpeedMaxDeviation[116]=/* Unknown default property type! */

Error in default property is caused probably by exception in decompiling hidecategories. There are some empty functions and missing default property.
I can provide all the necessary files. As for AA2.85 all files will be decrypted.

Alpha Protocol and Remember Me supported

Borderlands 2 [Status]

Tue, 25 Sep 2012 06:15:30 +0000

As requested, I have taken a look at Borderlands 2. The package opens in the present public version but the functions are not decompiled at all.

I have made some progress(~2 hours) on the decompiling the BL2 functions, so far this is how it looks:

Code:
static final simulated function float FindDeltaAngle(float A1, float A2)

{

    @OBJECT[1] = A2 - A1;

    // End:0x45 Loop:False

    if(@OBJECT[1] > 3.14)

    {

        @OBJECT[1] = @OBJECT[1] - 3.14 * 2.00;

        // This is an implied JumpToken;

        goto J0x6f;

        // End:0x6f Loop:False

        if(@OBJECT[1] < -3.14)

        {

            @OBJECT[1] = @OBJECT[1] + 3.14 * 2.00;

        }

        return @OBJECT[1];

        return ReturnValue;        

    }

}

Many functions are decompiled perfectly except for those using Let tokens(Assigments =) and Local variables as you see there are none but in the UDK build there is at least one local variable named Delta, e.g:

Code:
static final simulated function float FindDeltaAngle(float A1, float A2)

{

    local float Delta;

    Delta = A2 - A1;

    // End:0x55 Loop:False

    if(Delta > 3.14)

    {

        Delta = Delta - 3.14 * 2.00;

    }

    // End:0x8b

    else

    {

        // End:0x8b Loop:False

        if(Delta < -3.14)

        {

            Delta = Delta + 3.14 * 2.00;

        }

    }

    return Delta;

}

For as far as I know the local variables seem to have just dissapeared, although they've added a new array at the beginning of the functions with values I haven't figured out yet, perhaps they are the replacement for local variables.

I suppose I'll have to test more functions to get an idea of those changes

Mirrors Edge

Im not sure entirely whats going on here but there is alot of decompiler output in the scripts in tdgame.u and there is alot of script missing.

sample:

Code:
event Activated()

{

    local UIScene LocalScene;

    local WorldInfo WI;

    local TdPlayerController PC;

    local int CurrentDifficulty;

    local TdProfileSettings Profile;

    WI = GetWorldInfo();

    // End:0x58 Loop:False

    if(class(WI.switch(return @NULL) != none != ) != @NULL.@NULL) != @NULL || return)

    {

        {

            {

                {

                    {

                        {

APB: All Points Bulletin Support

Thu, 17 May 2012 10:42:03 +0000

APB: All Points Bulletin is supported in 1.1(Not released yet)

However like most supported games, it's not completely supported as in some objects might fail to decompile, but good enough to be useful. UE Explorer is mostly aimed to work 100% on Epic Games packages, not third parties, but I will do my best

For example with this game, all UnrealScript States code fails as well some bits of random functions, although most functions in APB are Native. Classes have some issues at the high level as well, but they are decompileable, things like Implements(...) might not be decompiled etc, and defaultproperties(unless you decompile them using Tables->Exports)

Will keep this thread updated when support is improved!

And here's an example, with a nice function but horrible state:

Code:
function bool CanPlayerInstantRestart()

{

    return m_bAllowInstantPlayerRestart;

}

state PendingMatch

{

Begin:

    @NULL(0)

    )

    stop;        

    sName

    @NULL(-65536)

    // Failed to decompile this line:

        // Failed to decompile this State's code.

        58

Index was out of range. Must be non-negative and less than the size of the collection.

...especially SCCT and SCDA support request if it's possible. SCDA-Offline is not encrypted - there is only small difference in file header. I can provide .u files from whole series if you need.

BTW. Great job - thank you...

Singularity

Sat, 31 Mar 2012 00:04:22 +0000

I hope its ok to create this thread

Singularity Non-Script Packages seem to open all fine, Script ones fail either at linking or at deserializing.

Would love to see this supported as it has a few unique things that are worth researching

If anyone wants to decompress RvGame.xxx or another script file be sure to use the -lzo switch on decompress.exe because of the compression

Infinity Blade 2
